Using the Arduino PID Library for precise position control of X and Y axis on RepScrap printer

I’ve updated the test code I’m using to manage my X and Y axis DC motor / linear encoder closed loop controller. I am currently using the Arduino PID Library by Brett Beauregard  for this, and having great success.  (Videos to come tomorrow.)I am NOT going to&nbs

Great Post Unix. I am now

Great Post Unix. I am now starting to learn more and more of the applications of PID other than line following. Had read of the applications, and now great to see HOW its really applied.

Oh, and downloaded that PID without PHD pdf file!

Hey UnixJust wanted to know

Hey Unix

Just wanted to know if you’ve made any progress on this? I’ve been looking to do the same although my thoughts were to output the step and direction pulses from a grbl equipped arduino to another arduino (probably a due for all of the interrrupts) and keep a running real time position target on each axis for the PID library. The Grbl will handle acceleration and turning the G codes into real time position targets. I believe that the PID loop could be tuned to give satisfactory performance without shuddering or lag.
